    Hi everyone...Awesome forum here!!!!!! I have 2 redmax eb7001's one of them is lacking power and once I shut it down its almost impossible to start again the other just doesnt start at all I have spark and fuel going to the cylinder just wont turn over. Any help is greatly appreciated. Thank you

    check the usual stuff...plugged muffler, dirty air filter, fouled plug, bad gas. try the mixture screws...1 turn from lightly seated is a good starting place. feel the fuel lines...if they feel like overcooked pasta, they need replaced. modern fuel eats fuel lines. are you sure the fuel/oil mix is correct?

    yeah the mixture is good... sometimes my guys tend to use 32:1 instead of 50:1 because theyre not paying attention. I didnt see any mixture screws on the carb though.

    Put in a new plug as a starter. I don't think they have carb adjustment on those unit. I would take the carb apart and clean it out since both units are failing you might have got dirt in the gas also dump all gas and start new so no chance of water.

    plug is good, carb is new, coil is new has good spark....compression is good this is driving me crazy. I had to rebuild this engine due to someone putting straight gas in it so everything internally is pretty much new.:confused:

    Will it run or start without the muffler being on?

    Check the compression on your cylinder there. You may have put to much gasket material or not enough for that matter when you rebuilt it.

    yank out your spark arestors...if they are cloged then thats your problem....take a blow torch to then and tap then aganst the work bench to clear the debris...

    120 is on the low side...did you replace the base gasket when rebuilding?
